Dead blow hammers are great for this when the rotor isn't stuck as a MOFO. Use a normal hammer and beat the piss out of it.

I had one stick badly. Soak... SOAK SOAK in Kroil or PB Blaster.. Do it for a day or so, then use a 5 pound mini-sledge. Hit the shit out of it.

Success at last. Saturated the thing with PB-Blaster, held tension with the puller, and used the hammer with a force I never thought I could muster. After a few hits, I was about to give up when I saw the puller fall on the ground, and I danced like an idiot in the parking lot when I saw that the hat had come off.

Here's the little bastard:
